This is a list of all virus species, including satellites and viroids. Excluded are other ranks, and other non-cellular life such as prions . Also excluded are common names and obsolete names for viruses.
The table below provides a list of human viral pathogens with transmission information and general facts about associated pathologies.
This is a list of infectious diseases arranged by name, along with the infectious agents that cause them, the vaccines that can prevent or cure them when they exist and their current status. Some on the list are vaccine-preventable diseases.
We’ll go over some of the main types, including how they’re spread, treated, and prevented. We’ll also list examples of each type of viral disease.
[ 11 ] Viruses spread in many ways. One transmission pathway is through disease-bearing organisms known as vectors: for example, viruses are often transmitted from plant to plant by insects that feed on plant sap, such as aphids; and viruses in animals can be carried by blood-sucking insects.
Virus. Viruses are microscopic organisms that can infect hosts, like humans, plants or animals. They’re a small piece of genetic information (DNA or RNA) inside of a protective shell (capsid). Some viruses also have an envelope. Viruses can’t reproduce without a host.
A viral infection can lead to a spectrum of symptoms from asymptomatic (no overt symptoms) to severe disease. People may get viruses by swallowing or inhaling them, by being bitten by insects, through sexual contact, or congenitally (passed by a pregnant person to the fetus).
What is a virus? What are viruses made of? What size are viruses? Are all viruses spherical in shape? Why are some viruses dangerous?
Viruses exist worldwide, but their spread is limited by inborn resistance, prior immunizing infections or vaccines, sanitary and other public health control measures, and prophylactic antiviral drugs. Zoonotic viruses pursue their biologic cycles chiefly in animals; humans are secondary or accidental hosts. These viruses are limited to areas ...
